In practice the borders to sew often coincide and in this case it is
difficult to specify the first and the last nodes of a border since
they coincide with the first and the last nodes of the other
border. To cope with this, manually \ref merging_nodes_page to fuse

beforehand. Two figures below illustrate this approach.
